Conducted EMS
Electro Magnetic Susceptibility is measured by injection of electri-
cal disturbances on the input terminals. No deviation outside the
V
Frequency range
0.15...300 MHz
Radiated EMS (Electro-Magnetic Fields)
Radiated EMS is measured according to test methods in
IEC Standard publ. 801-3. No deviation outside the V
band will occur under the following conditions:
Frequency range
0.01...200 MHz
200...1,000 MHz
1...12 GHz
ESD
Electro Static Discharge is tested according to IEC publ. 801-2.
No destruction will occur if the following voltage levels are ap-
plied to any of the terminal pins:

Air discharge
Contact discharge
EFT
output voltage regulation causing functional errors on the Printed
Board Assembly (PBA). The PKF power modules withstand EFT
levels of 0.5 kV keeping V
2.0 kV without destruction. Tested according to IEC publ. 801-4.
Output Ripple & Noise (V
Output ripple is measured as the peak to peak voltage of the
fundamental switching frequency.

Operating Information
Fuse Considerations
To prevent excessive current from flowing through the input
supply line, in the case of a short-circuit across the converter
input, an external fuse should be installed in the non-earthed
input supply line. We recommend using a fuse rated at
approximately 2 to 4 times the value calculated in the formula
below:
I
Refer to the fuse manufacturer for further information.
Remote Control (RC)
Turn-on or turn-off can be realized by using the RC-pin. If pin 11
is connected to pin 17 the power modules turns off. Normal
operation is achieved if pin 11 is open (NC). To ensure safe turn-
off the voltage difference between pin 11 and 17 shall be less than
1.0 V. RC is an open collector compatible input. A sink capacity
of 1mA is needed. (see fig. 1).
Turn-on/off Input Voltage
The power module monitors the input voltage and will turn on
and turn off at predetermined levels set by means of external
resistors.
